Spectacula

Ever found your theme doesn’t support threaded comments? Would you like it to 
be able to have P2 style live commenting on your site? Spectacu.la Discussion 
is a plugin that replaces the commenting code in your theme with a fully Ajaxed 
comments engine.
The plugin uses memory tables for fast caching within the database (no pesky 
permission setting for you to worry about here) and adjustible polling times to 
suit a wide range of server performance.
The plugin is also developer friendly, meaning that you can easily add styles to 
your theme so that should a user implement the plugin your meticulous design can 
be carried through. By default there are two styles that should work in most 
cases. Read below for further instructions.
Once installed this plug-in will replace your theme’s comments template with its 
own fully Ajax comment template. This allows both submission and update of 
comments without a page refres letting your visitors use it more as a chat room 
than the more traditional comment system. You can also roll up replied which can 
be told to trigger at any depth you feel is best using the settings page. Also 
available on the plug-ins admin page is the option to use another or no 
stylesheet, toggle the live updating of comments and change the refresh period 
for live update.
As of version 2 you can now easily add new stylesheets to the available list by 
either copying them into the plug-in’s style folder with a comment at the top of 
the sheet that looks like this /* comment style: Stylesheet name */ or adding a 
commenting.css to your theme or child theme. Once added they will then be listed 
in the dropdown menu that shows on the admin page.
The plugin is also, of course, Multisites compatible.
=The filters=
There are a few filters available for developers to intercept the javascript, 
paramerers passed to the javascript and the CSS file location
<ol>
<li>spec_comment_css 
Passes the URL of the stylesheet through to your function to replace 
with your own file.</li>
<li>spec_comment_js 
Passes the URL to the jQuery file that controls the roll up and a few 
other elements.</li>
<li>spec_comment_local_js 
Passes in an array of localisation strings that are passed to the 
jQuery code.</li>
</ol>
To replace the CSS file you could add something like the following to your 
functions.php that would point to a comments.css file in the folder of your 
current theme. This will then override any choice made by the user on the admin 
page.
<pre><code><?php
 add_filter('spec_comment_css', 'my_css_file');

 function my_css_file() {
 return get_bloginfo('template_directory') . '/comments.css';
 }

?>
</code></pre>
<h4>Warning</h4>
Every effort has been made to make this work with as wide a variety of themes as 
possible but we can’t cover every eventuality so some themes out there will 
cause problems with this plugin without you doing something to either the 
plug-in or the theme first. The most likely cause of problems is that some of 
the CSS in the theme conflicts with the CSS in the comments. There are various 
other areas where problems could arise, such as if the theme doesn’t call the 
comments.php using the <code>comments_template();</code> template tag or if your theme 
deals with comments in an unusual way, such as placing them in a sidebar or 
calling them in using Ajax that conflicts with our own. A missing or unusual 
DOCTYPE could cause problems too, in fact there are lots of things that could 
cause strangeness. However with most of the themes I’ve tested this with it has 
worked without issue straight out of the gate and even if it doesn’t look right 
you need only disable the plug-in to go back to how things were, so nothing’s 
lost.

With Ajax Post Carousel you can display posts as a carousel using jQuery for animations. The widget only preloads a few posts and Ajax is used to load more posts as the carousel advances (this is very useful when you have hundreds of posts).
The featured thumbnail of each post is used for the carousel, so at least WordPress 2.9 is required. The widget can be totally customized using CSS. Only the basic styles are defined so the carousel works properly.
Features
<ul>
<li>Posts can be selected from a category, a custom taxonomy or a post type.</li>
<li>Configurable number of posts shown in the carousel and number of preloaded posts (visible posts + posts loaded in the background)</li>
<li>Posts can be loaded in random order or using the default order (From most recent to oldest)</li>
<li>Carousel can be an endless loop</li>
<li>Title and excerpt can be shown. Thumbnail is always shown.</li>
<li>Can be used as a widget, a shortcode or a php function.</li>
</ul>
<h3>BETA</h3>
Be adviced we are releasing this software as beta software. 
Our initial intention is to gather feedback and collaboration.
After testing and approval the plugin will launch oficially.
Send us your comments to plugins@8manos.com
<h3>HOW TO</h3>
<ul>
<li>Carousels can be added using Widgets, Shortcodes or a PHP function.</li>
<li>You can use the default styles included in the plugin or use your own css. Explained below.</li>
</ul>
<h4>Widget</h4>
This is the easiest way to add carousels to your site. Just drag the “Ajax Post Carousel” widget to an available area and configure all settings.
<h4>Shortcode</h4>
You can use it to include carousels in your posts or pages. Add [apc-carousel] to use the default values.
All the options in the widget can also be used with the shortcode:
<ul>
<li>random: Accepts 0 or 1. (default 0)</li>
<li>visible_posts: Number of posts visible in the carousel. (default 3)</li>
<li>init_posts: Number of preloaded posts. Equals number of visible posts + number of posts in the background. (default 9)</li>
<li>show_title: Whether to show the title of the post. Accepts 0 or 1 (default 0)</li>
<li>show_excerpt: Whether to show the excerpt of the post. Accepts 0 or 1 (default 0)</li>
<li>loop: Accepts 0 or 1 (default 0)</li>
<li>post_type: Slug of the post type. Accepts ‘post’, ‘page’, ‘all’ or any custom post type. (default ‘post’)</li>
<li>category: Slug of the category. (default ‘all’)</li>
<li>Posts can be filtered by taxonomy using: taxonomy-slug=term-slug</li>
</ul>
Example:
[apc-carousel visible_posts=2 init_posts=8 show_title=1 show_excerpt=1 my-taxonomy=my-taxonomy-term]
<h4>PHP Function</h4>
The PHP function can be used in a theme template. The options and defaults are the same as in the Shortcode:
Ajax_Post_Carousel::show_carousel($random=0, $visible_posts=3, $init_posts=9, $show_title=0, $show_excerpt=0, $loop=0, $post_type=’post’, $category=’all’, $tax_filter=”)
$tax_filter uses this format: ‘my-tax-1=my-term-1&my-tax-2=my-term-2’
Example that returns the same output as the Shortcode example:
<h4>Use your own CSS</h4>
There are to ways to style the carousels using your own css.
<ol>
<li>Copy the css file from wp-content/plugins/ajax-post-carousel/ajax_post_carousel.css into your theme directory and edit the copy.</li>
<li>Define your own styles in your theme stylesheet. Just use the carousel id, so your rules have a higher priority than the rules from the plugin (for example: #apc_carousel_0 .apc_thumb{border:none;})</li>
</ol>
